Abstract

One of the main difficulties in applying heat storage systems utilising the latent heat of calcium chloride hexahydrate is the incongruent character of the melting of the hexahydrate. The heat storage capacity of the system is considerably diminished by the separation of [alpha]-CaCl2.4H2O, forming a new phase. In externally non-mixed systems the separation of the tetrahydrate is practically irreversible and this causes the rapid deterioration of the heat storage system. During the experiments described in this paper the effects of the change in composition of the CaCl2, 6H2O heat storage material, of the impurities (NaCl, KCl, MgCl2) and of thermoconvective flow on the formation of [alpha]-CaCl2.4H2O were investigated in externally non-mixed systems. It has been established that with a heat storage packing of more dilute (CaCl2.6·3H2O) total composition than the peritectic composition, favourable storage properties can be attained. To achieve this, the solid impurities have to be removed from the molten phase and the electric cable providing the heat input must be arranged to provide for adequate concentration equalisation by the convective thermal flow.
